Gosu cave 2

And the cave was warm.
In winter, it's about 12 degrees celsius. Why it's warmer than outside?
In summer, why inside the cave is cooler than outside, And I can't believe water made the Gosu cave.
I heard that water can make limestone melt from my mom.
The water dropped from the ceiling and I get water too. It was very cold. Gosu cave was very awesome.
I want to go there more! I want to go an area where we can't go.
